GHOSTSIGNS.CO.UK is a site dedicated to the hand painted advertising murals that we often see like ghosts of text on the sides of buildings. The site presents itself as,
a collaborative national effort to photograph, research and archive the remaining examples of hand painted wall advertising in the UK and Ireland.
The images of these ghostsigns are up on a Flickr group pool. See also HAT (History of Advertising Trust) web site which has a gallery.
